For the obstruction method in underground explosion engineering big gun hole, it comprises: step 1: after blast hole projectile filling terminates, and starts to prepare stemming batching; Step 2: the described stemming batching made in described step 1 is loaded in above-mentioned a kind of stemming spraying machine; Step 3: the spiral spray screw plug of described stemming spraying machine is entered in big gun hole, start described stemming spraying machine, described in described automatic control water equipment control, the weight of stemming batching is that 1:0.12 to 0.13 mixes with the weight ratio of water, obtain uniform stemming, even for described stemming slowly churning is entered big gun hole and hole wall surrounding by described spiral spray head.
The invention has the beneficial effects as follows:
(1) mud material source is wide, and low price, is convenient to draw materials.
(2) mud material uses in the engineering multiple-row blasting such as mine, water power, traffic, civil engineering, and have fine practicality, multiple-row blasting material energy reaches higher-strength within a short period of time, meets the requirement of job site.
(3) automatic control water system controls the water yield automatically, to stemming intelligent water supply, can ensure that in stemming, water content is stablized lastingly, ensure the viscosity of stemming, ensure that the effective use of material, can not occur that mud material is wasted because of weather reason, automatic control water system reduces investment in human resources greatly, alleviate construction burden, avoid pipe stopper pipe phenomenon and produce.
(4) spiral spray head ensures that in construction big gun hole wall periphery almost sprays mud simultaneously, ensure that the consistent, complete of big gun hole surrounding stemming intensity, and mud material bonding is more tight, not easily drops, and is conducive to improving construction speed, saves mud material.
(5) systems approach is loaded compared with existed system method in stemming scene of the present invention, not only increase stemming quality and multiple-row blasting efficiency, save staffing, improve working condition, ensure that construction safety simultaneously, substantially increase blasting quality, reduce blasting cost, obtain good economic benefit.
(6) the present invention is used for the horizontal multiple-row blasting in ten white velocity tunnel Blasting Excavation and the blocking of the up-hole in the back production of Da Ye Iron Mine, and plug-hole efficiency is high, and demolition effect is good, achieves good economic benefit and social benefit.
(7) stemming is changed into hydraulic pressure conveying is injected in big gun hole after stirring, the correct position that it is difficult to reach to up-hole or horizontal big gun hole can be eliminated, realize the automation that stemming is loaded, improve efficiency of construction, improve blocking quality, improve demolition effect, also improve work efficiency, bring considerable economic benefit to Underground Engineering Blasting.

Fig. 2 is the structural representation of spiral spray head of the present invention.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of stemming spraying machine, it comprises water storage device 2, water outlet water pipe 3, car base 4, stemming agitating device 5, goes out stemming pipe 6, spiral spray 7; Described water storage device 2 and described stemming agitating device 5 are all arranged on described car base 4; Be connected by described water outlet water pipe 3 between the water transport port of described water storage device 2 and the water inlet of described stemming agitating device 5; Go out stemming pipe 6 described in passing through between the mud mouth of described stemming agitating device 5 and described spiral spray 7 to be connected; Also comprise the suction pump be extracted into by water outlet water pipe 3 by the water in described water storage device 2 in described stemming agitating device 5; Described suction pump is arranged on the top of described water storage device 2; Also comprise and in described stemming agitating device 5, add the how many automatic control water equipment 1 of the water yield for controlling suction pump; Also comprise stemming hydraulic pressure delivery pump; Go out on stemming pipe 6 described in described stemming hydraulic pressure delivery pump is arranged on.
Further: it is 0.12:1 to 0.13:1 that described automatic control water equips the weight ratio that in 1 weight controlling to add water and described stemming agitating device 5, stemming is prepared burden.It is wet suitable that the composition of stemming need be done, and granularity is moderate, and sand factor is little.As stemming is too dry, it not easily adheres in big gun hole, and easy powdering comes off, and appoints the larger impact of explosive generation; Stemming is as too wet, then easy in the outflow of big gun hole, and does not reach the effect of blocking.Granularity as too large, Yi Heng in big gun hole, not easily plug-hole; As too thin, easily flow out from aperture.
